MAX A. SCHIENKE, O BAY SHORE, NEW YORK.

LAWN-SPRINKLER.

larmes.

Be it known that I, MAX A. SCHIENKE, ay

citizen of the United States, residin at Bay Shore, Long Island, in thecounty o Suffolk and State of New York, have invented cer tain new anduseful Improvements in Lawn- Sprinklers, of which the following is aspeciiication. I

An object of my invention is to provide an irrigating sprinkler whichwill cover a large area. of lawn by comparison with the area to throwsthe water.

A fnrther object is to so `construct the sprinkler that the normaloperation thereof acts to automatically cause the parts to be operatedto constantly change the center from which the sprays are directed.

With other objects in view,-which will be referred to,'my inventionconsists in the peculiar combination and novel arrangement of parts,such as will be hereinafter more fully described in connection with theaccompanying drawings and more particularly pointed out in the appendedclaims.

In the drawings Figurerl is a view in perspective showing my, improvedlawn sprinkler in use. `'Fig'. 2 is a vertical sectional view throughthe mechanism ofy the device. Fig. 3 is a sectional view of fragmentaryparts of the structure. Fig. 4 is a transversev sectional view'taken onthe line 4-4ofFig.2. '4 f The main structure of my improved lawnsprinkler comprises a tubular standard 1 which at its base has thesupporting legs 2, 2

lextended to the sides and spread apart to provide against lateraloverturning of this standard. The legs 2y have the supporting rolls 3mounted on the lower ends thereof to rest on and travel over the ground,andl an arm 4 formed to depend from the tubular standard 1 at a pointbetween the supporting legs 2 has an operating wheel 5. Journaledthereon.

An elbow 6, the structure of 'which is bet ter disclosed in Fig. 3, hasthe spur or spike 7 secured thereon tov be inserted into theground andto hold the elbow in the upright position as disclosed in Fig. 1. Thehose 8 has theyusual coupling 9 on the end thereof and this elbow 6 hasa screw-threaded end 10 provided to fit within and be connected by thecoupling 9 with the hose 8. 'The pipe 11 has one end thereof bent 'atright 'angles and this right angularly disposed portion is jour-Speeication of Letters Patent. Application med August 14, 1914. SerialNo. 856,840.

naled in the revoluble union 12 on the upper- .end ofthe elbow 6 so thatthe pipe llvhas Patented Feb. 8,1916.

free swinging movement in a circularl path around the point at whichthis elbow 6 is secured by the spike or pin 7. At its free end this pipe11 is connected by a union 13 with the lower end of the tubular standard1 and in this way the parts are so arranged that water is supplied fromthe hose 8 direct through the elbow 6 and pipe 11 tothe tubular standard1.

-A hollow stem lar standard 1 to have a liquid-tight connection aroundthe outside thereof and this stem 14 is stopped slightly short of thepoint of connection of the union 13 to the standard 1, and thus thesupply ofwater from the standard 1 is conducted to and through this stem14 to the head 15 provided on the upper end thereof. A plurality of arms16 made of tubing are connected with this had 15 to extend radiallytherefrom andto permit the 14 is mounted in the tubu-4v passage of waterfrom the head into the respective arms. Each of the arms 16 is bentslightly laterally at its outer end in a horizontal plane and thesprinkler heads 17 are so that the water conducted through the stem 4and through these arms 16 1s permitted'zto dpass from .the spray head ina shower anto fall upon the ground around the standard 1.

About midway alongfth'e'vertical extent `of the standard 1, a' portionof the wall thereofis'cut-away as at 18 and the stem 14 vhas the gearteeth-19'providedA theremounted on the extreme ends of the arms 16around adjacent this cut-away portion 18.

A shaft 20 is journaled in suitablebearings provided on the exterior ofthe standard 1 and at its upper end-hasa` gear wheel .By v'reason of thefact that the arms'l I are curved slightly at their youter ends and thespray heads 17 are mounted on these curved ends, the spray or showerfrom the impact is vmade by `the water discharged therefrom againstthe-'air to cause the head 15 and consequently the stem 14 to berevolvedwithin the tubular standard 1. This revolution of the stem'14 causes thetoothed spray heads 17 is directed laterally and an portion 19 to becarried around and throughthe engagement of the teeth of the gear wheel2l with the teeth 19 of this stem 14e.. the sha-ft 2() is revolved andby. reason of the fact that the iiiiter gea-rs 22 and 23 are in mesh arotary motion is transmitted to the operating wheel This operating wheel5, as has been liereinbefore set forth, is arranged in Contact with theground of the lawn and through the turning thereof animpelling foi-ee isgiven to the standard 1 to Cause this standard to be moved upon theoperating` wheel 5 and the supporting-wheels 3 iii a circular patharound the connection at 12 with the elbow 6, the radius of which pathis governed by the length of the pipe 11.' From the foregoing itxwillbe.seen that I have provided an irrigating sprinkler of the lawn sprinklertype which has the parts thereof so arranged that aii area is coveredwhich is considerably in excess of that which is sprinkled by a reactionsprayer of the stationaiy-standard type, and also it will be seen thatthe operation ofth'e device is automatic during the normal use as asprinkler.

While I have herein shown and described one speoiie form of iiiyinvention, it will be understood that slight changes might be made intheform and arrangement ofthe several parts without departing from thespirit and Scope of my invention, and hence I do not wish to be limitedthereto except for such limitations as the claims may impath, a hollowstem revolubly mounted iii said standard, arevolving spray `structurecarried by said stem above the upper eiid of said standard, an operatingwheel carried by said supporting standard to engage the ground,gearteeth formed on said operating wheel,` gear teeth formed on saidstem. substantially mid-way its vertical extent, said standard being cutaway at al point interii'iediate its upper and lower ends adj aeeut thegear teet-hon-said stein, bearings mounted oii said standard, a shaftjournaled through said bearings,lone end of said shaft carrying a gearwheel in mesh with the gear teeth on said operating wheel, and the otherend of said shaft carrying a gear wheel in mesh with the teeth oii saidstem, whereby the rotation of said Stein by Said spray struetui'e willcause a similar movement of said supporting wheel,` substantially asdescribed,

2. In a movable lawn sprinkler, a hollow supporting standard, anoperating means carried by said standard to engage the ground, alioll'ow stem mounted in said standard, a spray structure caiir'ied bysaid stein, gear teeth formed on said stem, said standard provided witha cut-out intermediate its ends adjacent the gear teeth, gear teethformed on Said operating wheel, bearings, a shaft joiirnaled throughsaid bearings, a gear wheel carried on said shat't meshing with thevgear teeth on said operating wheel, a gear wheel carried on said shaftprojecting through the cut-out in said standard and meshing with thegear teeth on. said stem, whereby rotation of said stem will cause asimilar movement of said operating wheel, Substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
